(b) The tumor cells were basaloid, small, hyperchromatic, and mostly uniform. Nodules exhibited peripheral palisading cells and retraction artifact (arrows). (c) Islands of mucin (arrows) were present within the tumor. (d) Some tumor nodules exhibited dark-brown pigment centrally. (e) The pigment was coarse and acellular. (f) Desmoplastic stroma harboring cholesterol clefts (arrows) and clumps of pigment was seen in nodule centers.
